I've encountered this error when I tried to access the 'canvas' outside of onDraw()

    private Canvas canvas;

    @Override
    protected void onDraw(Canvas canvas) {
        this.canvas = canvas;
        ....... }

    private class ScaleListener extends ScaleGestureDetector.SimpleOnScaleGestureListener {
        @Override
        public boolean onScale(ScaleGestureDetector detector) { 
            canvas.save(); // here

A very bad practice :/

It seems you're actually talking about an MVC (Model-View-Controller) pattern, where logic is separated into various "tiers". Django, as a framework, follows MVC (loosely). You have models that contain your business logic and relate directly to tables in your database, views which in effect act like the controller, handling requests and returning responses, and finally, templates which handle presentation.

Django isn't just one of these, it is a complete framework for application development and provides all the tools you need for that purpose.

Frontend vs Backend is all semantics. You could potentially build a Django app that is entirely "backend", using its built-in admin contrib package to manage the data for an entirely separate application. Or, you could use it solely for "frontend", just using its views and templates but using something else entirely to manage the data. Most usually, it's used for both. The built-in admin (the "backend"), provides an easy way to manage your data and you build apps within Django to present that data in various ways. However, if you were so inclined, you could also create your own "backend" in Django. You're not forced to use the default admin.

Short version: Create styles only once, use them everywhere.

Long version: use a method to create the styles you need (beware of the limit on the amount of styles).

private static Map<String, CellStyle> styles;

private static Map<String, CellStyle> createStyles(Workbook wb){
        Map<String, CellStyle> styles = new HashMap<String, CellStyle>();
        DataFormat df = wb.createDataFormat();

        CellStyle style;
        Font headerFont = wb.createFont();
        headerFont.setBoldweight(Font.BOLDWEIGHT_BOLD);
        headerFont.setFontHeightInPoints((short) 12);
        style = createBorderedStyle(wb);
        style.setAlignment(CellStyle.ALIGN_CENTER);
        style.setFont(headerFont);
        styles.put("style1", style);

        style = createBorderedStyle(wb);
        style.setAlignment(CellStyle.ALIGN_CENTER);
        style.setFillForegroundColor(IndexedColors.LIGHT_CORNFLOWER_BLUE.getIndex());
        style.setFillPattern(CellStyle.SOLID_FOREGROUND);
        style.setFont(headerFont);
        style.setDataFormat(df.getFormat("d-mmm"));
        styles.put("date_style", style);
        ...
        return styles;
    }

you can also use methods to do repetitive tasks while creating styles hashmap

private static CellStyle createBorderedStyle(Workbook wb) {
        CellStyle style = wb.createCellStyle();
        style.setBorderRight(CellStyle.BORDER_THIN);
        style.setRightBorderColor(IndexedColors.BLACK.getIndex());
        style.setBorderBottom(CellStyle.BORDER_THIN);
        style.setBottomBorderColor(IndexedColors.BLACK.getIndex());
        style.setBorderLeft(CellStyle.BORDER_THIN);
        style.setLeftBorderColor(IndexedColors.BLACK.getIndex());
        style.setBorderTop(CellStyle.BORDER_THIN);
        style.setTopBorderColor(IndexedColors.BLACK.getIndex());
        return style;
    }

then, in your "main" code, set the style from the styles map you have.

Cell cell = xssfCurrentRow.createCell( intCellPosition );       
cell.setCellValue( blah );
cell.setCellStyle( (CellStyle) styles.get("style1") );

Define mappings for both behaviors, because both are useful!

• Completely clear the search buffer (e.g., pressing n for next match will not resume search)
• Retain search buffer, and toggle highlighting the search results on/off/on/... (e.g., pressing n will resume search, but highlighting will be based on current state of toggle)

" use double-Esc to completely clear the search buffer
nnoremap <silent> <Esc><Esc> :let @/ = ""<CR>
" use space to retain the search buffer and toggle highlighting off/on
nnoremap <silent> <Space> :set hlsearch!<CR>

Object Serialization uses the Serializable and Externalizable interfaces. A Java object is only serializable. if a class or any of its superclasses implements either the java.io.Serializable interface or its subinterface, java.io.Externalizable. Most of the java class are serializable.

• NotSerializableException: packageName.ClassName « To participate a Class Object in serialization process, The class must implement either Serializable or Externalizable interface.

Serializable Interface

Object Serialization produces a stream with information about the Java classes for the objects which are being saved. For serializable objects, sufficient information is kept to restore those objects even if a different (but compatible) version of the implementation of the class is present. The Serializable interface is defined to identify classes which implement the serializable protocol:

package java.io;

public interface Serializable {};

• The serialization interface has no methods or fields and serves only to identify the semantics of being serializable. For serializing/deserializing a class, either we can use default writeObject and readObject methods (or) we can overriding writeObject and readObject methods from a class.
• JVM will have complete control in serializing the object. use transient keyword to prevent the data member from being serialized.
• Here serializable objects is reconstructed directly from the stream without executing
• InvalidClassException « In deserialization process, if local class serialVersionUID value is different from the corresponding sender's class. then result's in conflict as java.io.InvalidClassException: com.github.objects.User; local class incompatible: stream classdesc serialVersionUID = 5081877, local class serialVersionUID = 50818771
• The values of the non-transient and non-static fields of the class get serialized.

Externalizable Interface

For Externalizable objects, only the identity of the class of the object is saved by the container; the class must save and restore the contents. The Externalizable interface is defined as follows:

package java.io;

public interface Externalizable extends Serializable
{
    public void writeExternal(ObjectOutput out)
        throws IOException;

    public void readExternal(ObjectInput in)
        throws IOException, java.lang.ClassNotFoundException;
}

• The Externalizable interface has two methods, an externalizable object must implement a writeExternal and readExternal methods to save/restore the state of an object.
• Programmer has to take care of which objects to be serialized. As a programmer take care of Serialization So, here transient keyword will not restrict any object in Serialization process.
• When an Externalizable object is reconstructed, an instance is created using the public no-arg constructor, then the readExternal method called. Serializable objects are restored by reading them from an ObjectInputStream.

• OptionalDataException « The fields MUST BE IN THE SAME ORDER AND TYPE as we wrote them out. If there is any mismatch of type from the stream it throws OptionalDataException.

  @Override public void writeExternal(ObjectOutput out) throws IOException {
      out.writeInt( id );
      out.writeUTF( role );
      out.writeObject(address);
  }
  @Override public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException {
      this.id = in.readInt();
      this.address = (Address) in.readObject();
      this.role = in.readUTF();
  }
  

• The instance fields of the class which written (exposed) to ObjectOutput get serialized.

Example « implements Serializable

class Role {
    String role;
}
class User extends Role implements Serializable {

    private static final long serialVersionUID = 5081877L;
    Integer id;
    Address address;

    public User() {
        System.out.println("Default Constructor get executed.");
    }
    public User( String role ) {
        this.role = role;
        System.out.println("Parametarised Constructor.");
    }
}

class Address implements Serializable {

    private static final long serialVersionUID = 5081877L;
    String country;
}

Example « implements Externalizable

class User extends Role implements Externalizable {

    Integer id;
    Address address;
    // mandatory public no-arg constructor
    public User() {
        System.out.println("Default Constructor get executed.");
    }
    public User( String role ) {
        this.role = role;
        System.out.println("Parametarised Constructor.");
    }

    @Override
    public void writeExternal(ObjectOutput out) throws IOException {
        out.writeInt( id );
        out.writeUTF( role );
        out.writeObject(address);
    }
    @Override
    public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException {
        this.id = in.readInt();
        this.address = (Address) in.readObject();
        this.role = in.readUTF();
    }
}

To adjust the width, you could wrap your TextField with a Container widget, like so:

Container(              
  width: 100.0,
  child: TextField()
)

I'm not really sure what you're after when it comes to the height of the TextField but you could definitely have a look at the TextStyle widget, with which you can manipulate the fontSize and/or height

Container(              
  width: 100.0,
  child: TextField(                                 
    style: TextStyle(
      fontSize: 40.0,
      height: 2.0,
      color: Colors.black                  
    )
  )
)

Bear in mind that the height in the TextStyle is a multiplier of the font size, as per comments on the property itself:

The height of this text span, as a multiple of the font size.

When [height] is null or omitted, the line height will be determined by the font's metrics directly, which may differ from the fontSize. When [height] is non-null, the line height of the span of text will be a multiple of [fontSize] and be exactly fontSize * height logical pixels tall.

Last but not least, you might want to have a look at the decoration property of you TextField, which gives you a lot of possibilities

EDIT: How to change the inner padding/margin of the TextField

You could play around with the InputDecoration and the decoration property of the TextField. For instance, you could do something like this:

TextField(                                
    decoration: const InputDecoration(
        contentPadding: const EdgeInsets.symmetric(vertical: 40.0),
    )
)

Create a file named filesize.cmd (and put into folder C:\Windows\System32):

@echo %~z1

This worked for me

//Sentence has quotes
string nameSentence = "Take my name \"Wesley\" out of quotes";
//Get the index before the quotes`enter code here`
int begin = nameSentence.LastIndexOf("name") + "name".Length;
//Get the index after the quotes
int end = nameSentence.LastIndexOf("out");
//Get the part of the string with its quotes
string name = nameSentence.Substring(begin, end - begin);
//Remove its quotes
string newName = name.Replace("\"", "");
//Replace new name (without quotes) within original sentence
string updatedNameSentence = nameSentence.Replace(name, newName);

//Returns "Take my name Wesley out of quotes"
return updatedNameSentence;

If you take a look at the official docs, you'll see right below append, extend. That's what your looking for.

There's also itertools.chain if you are more interested in efficient iteration than ending up with a fully populated data structure.

Joe's approach is actually the most effective means that I have found for doing this conversation. To elaborate a little bit more on it, you should right click on the project in the package explorer in eclipse and then select to delete it without removing directory or its contents. Next, you select to create a Java project (File -> New -> Java Project) and in the Contents part of the New Java Project dialog box, select 'Create project from existing source'.

The advantage this approach is that source folders will be properly identified. I found that mucking around with the .project file can lead to the entire directory being considered a source folder which is not what you want.

In C++ (but not plain C), it's perfectly legal to typedef a type twice, so long as both definitions are completely identical:

// foo.h
struct A{};
typedef A *PA;

// bar.h
struct A;  // forward declare A
typedef A *PA;
void func(PA x);

// baz.cc
#include "bar.h"
#include "foo.h"
// We've now included the definition for PA twice, but it's ok since they're the same
...
A x;
func(&x);

Instead of os.path.isfile, suggested by others, I suggest using os.path.exists, which checks for anything with that name, not just whether it is a regular file.

Thus:

if not os.path.exists(filename):
    file(filename, 'w').close()

Alternatively:

file(filename, 'w+').close()

The latter will create the file if it exists, but not otherwise. It will, however, fail if the file exists, but you don't have permission to write to it. That's why I prefer the first solution.

A simple JSF Url Prettyfier filter based in the steps of BalusC's answer. The filter forwards all the requests starting with the /ui path (supposing you've got all your xhtml files stored there) to the same path, but adding the xhtml suffix.

public class UrlPrettyfierFilter implements Filter {

    private static final String JSF_VIEW_ROOT_PATH = "/ui";

    private static final String JSF_VIEW_SUFFIX = ".xhtml";

    @Override
    public void destroy() {

    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        HttpServletRequest httpServletRequest = ((HttpServletRequest) request);
        String requestURI = httpServletRequest.getRequestURI();
        //Only process the paths starting with /ui, so as other requests get unprocessed. 
        //You can register the filter itself for /ui/* only, too
        if (requestURI.startsWith(JSF_VIEW_ROOT_PATH) 
                && !requestURI.contains(JSF_VIEW_SUFFIX)) {
            request.getRequestDispatcher(requestURI.concat(JSF_VIEW_SUFFIX))
                .forward(request,response);
        } else {
            chain.doFilter(httpServletRequest, response);
        }
    }

    @Override
    public void init(FilterConfig arg0) throws ServletException {

    }

}

In python, you can put ‘j’ or ‘J’ after a number to make it imaginary, so you can write complex literals easily:

>>> 1j
1j
>>> 1J
1j
>>> 1j * 1j
(-1+0j)

The ‘j’ suffix comes from electrical engineering, where the variable ‘i’ is usually used for current. (Reasoning found here.)

The type of a complex number is complex, and you can use the type as a constructor if you prefer:

>>> complex(2,3)
(2+3j)

A complex number has some built-in accessors:

>>> z = 2+3j
>>> z.real
2.0
>>> z.imag
3.0
>>> z.conjugate()
(2-3j)

Several built-in functions support complex numbers:

>>> abs(3 + 4j)
5.0
>>> pow(3 + 4j, 2)
(-7+24j)

The standard module cmath has more functions that handle complex numbers:

>>> import cmath
>>> cmath.sin(2 + 3j)
(9.15449914691143-4.168906959966565j)

just use frame.setVisible(false); frame.setVisible(true); I've had this problem with JLabels with images, and this solved it

Add the following to the top of your file # coding=utf-8

If you go to the link in the error you can seen the reason why:

Defining the Encoding

Python will default to ASCII as standard encoding if no other encoding hints are given. To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as: # coding=

?+?+?/?/?/? will let you navigate split panes in the direction of the arrow, i.e. when using ?+D to split panes vertically, ?+?+? and ?+?+? will let you switch between the panes.

I think you can simply add the oneside option the book class?

i.e.

\documentclass[oneside]{book}

Although I didn't test it :)

If each part have the same lines number, for example 22, here my solution:
split --numeric-suffixes=2 --additional-suffix=.txt -l 22 file.txt file
and you obtain file2.txt with the first 22 lines, file3.txt the 22 next line…

Thank @hamruta-takawale, @dror-s and @stackoverflowuser2010

I'd like to point out. maybe this just happens to me, HOWEVER, when I use this.removeAllFiles() in dropzone, it fires the event COMPLETE and this blows, what I did was check if the fileData was empty or not so I could actually submit the form.

Same to me. The name of the mapping class was Mbean but the tag root name was mbean so I had to add the annotation:

@XmlRootElement(name="mbean")
public class MBean { ... }

If it's an input element you can write something like.... <input type="radio" [checked]="condition"> The value of condition must be true or false.

Also for style attributes... <h4 [style.color]="'red'">Some text</h4>

You may not necessarily want/need to stash your work/files in your working directory but instead simply get rid of them completely. The command git clean will do this for you.

Some common use cases for doing this would be to remove cruft that has been generated by merges or external tools or remove other files so that you can run a clean build.

Keep in mind you will want to be very cautious of this command, since its designed to remove files from your local working directory that are NOT TRACKED. if you suddently change your mind after executing this command, there is no going back to see the content of the files that were removed. An alternative which is safer is to execute

git stash --all

which will remove everything but save it all in a stash. This stash can then later be used.

However, if you truly DO want to remove all the files and clean your working directory, you should execute

git clean -f -d

This will remove any files and also any sub-directories that don't have any items as a result of the command. A smart thing to do before executing the git clean -f -d command is to run

git clean -f -d -n

which will show you a preview of what WILL be removed after executing git clean -f -d

So here is a summary of your options from most aggressive to least aggressive

Option 1: Remove all files locally(Most aggressive)

git clean -f -d

Option 2: Preview the above impact(Preview most aggressive)

git clean -f -d -n

Option 3: Stash all files (Least aggressive)

`git stash --all` 

This should do it:

Type myType = myObject.GetType();
IList<PropertyInfo> props = new List<PropertyInfo>(myType.GetProperties());

foreach (PropertyInfo prop in props)
{
    object propValue = prop.GetValue(myObject, null);

    // Do something with propValue
}

If you have ERROR 1064 (42000) or ERROR 1046 (3D000): No database selected in Mysql 5.7, you must specify the location of the user table, the location is mysql.table_name Then the code will work.

sudo mysql -u root -p

UPDATE mysql.user SET authentication_string=password('elephant7') WHERE user='root';

Whilst I'm sure POCO means Plain Old Class Object or Plain Old C Object to 99.9% of people here, POCO is also Animator Pro's (Autodesk) built in scripting language.

Below works (in my limited testing) by doing deep compare between two object hierarchies. In handles various cases including the cases when objects themselves or their attributes are dictionaries.

def deep_comp(o1:Any, o2:Any)->bool:
    # NOTE: dict don't have __dict__
    o1d = getattr(o1, '__dict__', None)
    o2d = getattr(o2, '__dict__', None)

    # if both are objects
    if o1d is not None and o2d is not None:
        # we will compare their dictionaries
        o1, o2 = o1.__dict__, o2.__dict__

    if o1 is not None and o2 is not None:
        # if both are dictionaries, we will compare each key
        if isinstance(o1, dict) and isinstance(o2, dict):
            for k in set().union(o1.keys() ,o2.keys()):
                if k in o1 and k in o2:
                    if not deep_comp(o1[k], o2[k]):
                        return False
                else:
                    return False # some key missing
            return True
    # mismatched object types or both are scalers, or one or both None
    return o1 == o2

This is a very tricky code so please add any cases that might not work for you in comments.

The folder is part of the URL you set when you create request: "ftp://www.contoso.com/test.htm". If you use "ftp://www.contoso.com/wibble/test.htm" then the file will be uploaded to a folder named wibble.

You may need to first use a request with Method = WebRequestMethods.Ftp.MakeDirectory to make the wibble folder if it doesn't already exist.

var arr = Convert.ToString(val, 2).ToArray();
var myVal = arr[21];

...did not produce the results I was looking for. In 'myVal' above, the value stored in the array in position 21 was '0'. It should have been a '1'. I'm not sure why I received an inaccurate value for this and it baffled me until I found another way in C# to convert an INT to a bit array:

int val = 2097152;
var arr = new BitArray(BitConverter.GetBytes(val));
var myVal = arr[21];

This produced the result 'true' as a boolean value for 'myVal'.

I realize this may not be the most efficient way to obtain this value, but it was very straight forward, simple, and readable.

Basically alter API header response by adding following additional parameters.

Access-Control-Allow-Credentials: true

Access-Control-Allow-Origin: *

But this is not good solution when it comes to the security

To create a user with sudo privileges is to put the user into /etc/sudoers, or make the user a member of a group specified in /etc/sudoers. And to make it password-less is to additionally specify NOPASSWD in /etc/sudoers.

Example of /etc/sudoers:

## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL

## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL

## Same thing without a password
%wheel  ALL=(ALL)       NOPASSWD: ALL

And instead of fiddling with /etc/sudoers file, we can create a new file in /etc/sudoers.d/ directory since this directory is included by /etc/sudoers by default, which avoids the possibility of breaking existing sudoers file, and also eliminates the dependency on the content inside of /etc/sudoers.

To achieve above in Ansible, refer to the following:

- name: sudo without password for wheel group
  copy:
    content: '%wheel ALL=(ALL:ALL) NOPASSWD:ALL'
    dest: /etc/sudoers.d/wheel_nopasswd
    mode: 0440

You may replace %wheel with other group names like %sudoers or other user names like deployer.

There is no hard and fast rule.

Here are some rules to make code thread safe in .NET and why these are not good rules:

1. Function and all functions it calls must be pure (no side effects) and use local variables. Although this will make your code thread-safe, there is also very little amount of interesting things you can do with this restriction in .NET.
2. Every function that operates on a common object must lock on a common thing. All locks must be done in same order. This will make the code thread safe, but it will be incredibly slow, and you might as well not use multiple threads.
3. ...

There is no rule that makes the code thread safe, the only thing you can do is make sure that your code will work no matter how many times is it being actively executed, each thread can be interrupted at any point, with each thread being in its own state/location, and this for each function (static or otherwise) that is accessing common objects.

While in insert mode, you can use Ctrl-R {register}, where register can be:

• + for the clipboard,
• * for the X clipboard (last selected text in X),
• " for the unnamed register (last delete or yank in Vim),
• or a number of others (see :h registers).

Ctrl-R {register} inserts the text as if it were typed.

Ctrl-R Ctrl-O {register} inserts the text with the original indentation.

Ctrl-R Ctrl-P {register} inserts the text and auto-indents it.

Ctrl-O can be used to run any normal mode command before returning to insert mode, so
Ctrl-O "+p can also be used, for example.

For more information, view the documentation with :h i_ctrl-r

As the first answer indicated, currently there is no way to rename components so we're all just talking about work-arounds! This is what i do:

1. Create the new component you liked.

   ng generate component newName

2. Use Visual studio code editor or whatever other editor to then conveniently move code/pieces side by side!

3. In Linux, use grep & sed (find & replace) to find/replaces references.

   grep -ir "oldname"

   cd your folder

   sed -i 's/oldName/newName/g' *

I would suggest the following pattern:

document.getElementById("foo").onsubmit = function(e) {
    if (document.getElementById("test").value == "test") {
        return true;
    } else {
        e.preventDefault();
    }
}

<form id="foo">
    <input id="test"/>
    <input type="submit"/>
</form>

...unless I'm missing something.

onMessageReceived(RemoteMessage remoteMessage) method called based on the following cases.

• FCM Response With notification and data block:

{
  
"to": "device token list",
  "notification": {
    "body": "Body of Your Notification",
    "title": "Title of Your Notification"
  },
  "data": {
    "body": "Body of Your Notification in Data",
    "title": "Title of Your Notification in Title",
    "key_1": "Value for key_1",
    "image_url": "www.abc.com/xyz.jpeg",
    "key_2": "Value for key_2"
  }
}

1. App in Foreground:

onMessageReceived(RemoteMessage remoteMessage) called, shows LargeIcon and BigPicture in the notification bar. We can read the content from both notification and data block

2. App in Background:

onMessageReceived(RemoteMessage remoteMessage) not called, system tray will receive the message and read body and title from notification block and shows default message and title in the notification bar.

• FCM Response With only data block:

In this case, removing notification blocks from json

{
  
"to": "device token list",
  "data": {
    "body": "Body of Your Notification in Data",
    "title": "Title of Your Notification in Title",
    "key_1": "Value for key_1",
    "image_url": "www.abc.com/xyz.jpeg",
    "key_2": "Value for key_2"
  }
}

Solution for calling onMessageReceived()

1. App in Foreground:

onMessageReceived(RemoteMessage remoteMessage) called, shows LargeIcon and BigPicture in the notification bar. We can read the content from both notification and data block

2. App in Background:

onMessageReceived(RemoteMessage remoteMessage) called, system tray will not receive the message because of notification key is not in the response. Shows LargeIcon and BigPicture in the notification bar

Code

 private void sendNotification(Bitmap bitmap,  String title, String 
    message, PendingIntent resultPendingIntent) {

    NotificationCompat.BigPictureStyle style = new NotificationCompat.BigPictureStyle();
    style.bigPicture(bitmap);

    Uri defaultSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
    String NOTIFICATION_CHANNEL_ID = mContext.getString(R.string.default_notification_channel_id);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "channel_name", NotificationManager.IMPORTANCE_HIGH);

        notificationManager.createNotificationChannel(notificationChannel);
    }
    Bitmap iconLarge = BitmapFactory.decodeResource(mContext.getResources(),
            R.drawable.mdmlogo);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(mContext, NOTIFICATION_CHANNEL_ID)
            .setSmallIcon(R.drawable.mdmlogo)
            .setContentTitle(title)
            .setAutoCancel(true)
            .setSound(defaultSound)
            .setContentText(message)
            .setContentIntent(resultPendingIntent)
            .setStyle(style)
            .setLargeIcon(iconLarge)
            .setWhen(System.currentTimeMillis())
            .setPriority(Notification.PRIORITY_MAX)
            .setChannelId(NOTIFICATION_CHANNEL_ID);


    notificationManager.notify(1, notificationBuilder.build());

For quick overview comparisons, I really like this website, that has many comparison pages, eg AWS DynamoDB vs MongoDB; http://db-engines.com/en/system/Amazon+DynamoDB%3BMongoDB

1) Correct

2) You can think of that one as "read only" list, where you don't care about the type of the items.Could e.g. be used by a method that is returning the length of the list.

3) T, E and U are the same, but people tend to use e.g. T for type, E for Element, V for value and K for key. The method that compiles says that it took an array of a certain type, and returns an array of the same type.

4) You can't mix oranges and apples. You would be able to add an Object to your String list if you could pass a string list to a method that expects object lists. (And not all objects are strings)

As much as I love this framework, I hate when it acts like crap.

DB::enableQueryLog() is totally useless. DB::listen is equally useless. It showed part of the query when I said $query->count(), but if I do $query->get(), it has nothing to say.

The only solution that appears to work consistently is to intentionally put some syntax or other error in the ORM parameters, like an nonexistent column/table name, run your code on the command line while in debug mode, and it will spit out the SQL error with the full frickin' query finally. Otherwise, hopefully the error appears in the log file if ran from the web server.

chmod 400 mykey.pem

ssh -i mykey.pem [email protected]

Will connect you over ssh using a .pem file to any server.

in the "Ouput Window". you can usually do CTRL-ALT-O to make it visible. Or through menus using View->Output.

You can use your own customize class based on the concept, here the code snippet which you can use to do the stuff

/*
*   Stack implementation in JavaScript

function Stack() {
  this.top = null;
  this.count = 0;

  this.getCount = function() {
    return this.count;

  this.getTop = function() {
    return this.top;
  }

  this.push = function(data) {

Try this: .aspx page

<td>  
<asp:TextBox ID="TextBox1" runat="server" AutoPostBack="True"OnTextChanged="TextBox1_TextChanged"></asp:TextBox>  
<asp:AutoCompleteExtender ServiceMethod="GetCompletionList" MinimumPrefixLength="1"  
   CompletionInterval="10" EnableCaching="false" CompletionSetCount="1" TargetControlID="TextBox1"  
   ID="AutoCompleteExtender1" runat="server" FirstRowSelected="false">  
      </asp:AutoCompleteExtender>  

Now To auto populate from database :

public static List<string> GetCompletionList(string prefixText, int count)  
    {  
        return AutoFillProducts(prefixText);  

    }  

    private static List<string> AutoFillProducts(string prefixText)  
    {  
        using (SqlConnection con = new SqlConnection())  
        {  
            con.ConnectionString = ConfigurationManager.ConnectionStrings["Conn"].ConnectionString;  
            using (SqlCommand com = new SqlCommand())  
            {  
                com.CommandText = "select ProductName from ProdcutMaster where " + "ProductName like @Search + '%'";  
                com.Parameters.AddWithValue("@Search", prefixText);  
                com.Connection = con;  
                con.Open();  
                List<string> countryNames = new List<string>();  
                using (SqlDataReader sdr = com.ExecuteReader())  
                {  
                    while (sdr.Read())  
                    {  
                        countryNames.Add(sdr["ProductName"].ToString());  
                    }  
                }  
                con.Close();  
                return countryNames;  
            }  
        }  
    }  

Now:create a stored Procedure that fetches the Product details depending on the selected product from the Auto Complete Text Box.

Create Procedure GetProductDet  
(  
@ProductName varchar(50)    
)  
as  
begin  
Select BrandName,warranty,Price from ProdcutMaster where ProductName=@ProductName  
End   

Create a function name to get product details ::

private void GetProductMasterDet(string ProductName)  
    {  
        connection();  
        com = new SqlCommand("GetProductDet", con);  
        com.CommandType = CommandType.StoredProcedure;  
        com.Parameters.AddWithValue("@ProductName", ProductName);  
        SqlDataAdapter da = new SqlDataAdapter(com);  
        DataSet ds=new DataSet();  
        da.Fill(ds);  
        DataTable dt = ds.Tables[0];  
        con.Close();  
        //Binding TextBox From dataTable  
        txtbrandName.Text =dt.Rows[0]["BrandName"].ToString();  
        txtwarranty.Text = dt.Rows[0]["warranty"].ToString();  
        txtPrice.Text = dt.Rows[0]["Price"].ToString();   
    }

Auto post back should be true

<asp:TextBox ID="TextBox1" runat="server" AutoPostBack="True" OnTextChanged="TextBox1_TextChanged"></asp:TextBox>

Now, Just call this function

protected void TextBox1_TextChanged(object sender, EventArgs e)  
  {  
      //calling method and Passing Values  
      GetProductMasterDet(TextBox1.Text);  
  }

I would like a system where I can point a video camera at some sailing boats, all of which have large, identifiable numbers on them, and have it identify the boats and send a tweet when they sail past a video camera.

Okay you must try this guys it works for me:

1. Open SDK Manager and Install SDK build tools 22.0.1
2. Sync gradle That'all

This will happen if the host page is HTTPS and the included javascript source path is HTTP. The two protocols must be the same, HTTPS. The tell tail sign would be to check under Firebug and notice that the JS is "denied access".

//Fields
String myID;
int myversion = 0;


myversion = Integer.valueOf(android.os.Build.VERSION.SDK);
if (myversion < 23) {
        TelephonyManager mngr = (TelephonyManager) 
getSystemService(Context.TELEPHONY_SERVICE);
        myID= mngr.getDeviceId();
    }
    else
    {
        myID = 
Settings.Secure.getString(getApplicationContext().getContentResolver(), 
Settings.Secure.ANDROID_ID);
    }

Yes, Secure.ANDROID_ID is unique for each device.

I think the answer from cheez (https://stackoverflow.com/users/122933/cheez) is the easiest and most effective one. I'd elaborate a little bit over it so it would not modify a numpy function for the whole session period.

My suggestion is below. I´m using it to download the reuters dataset from keras which is showing the same kind of error:

old = np.load
np.load = lambda *a,**k: old(*a,**k,allow_pickle=True)

from keras.datasets import reuters
(train_data, train_labels), (test_data, test_labels) = reuters.load_data(num_words=10000)

np.load = old
del(old)

When you join the new thread in the main thread, it will wait until the thread finishes, so the GUI will block even though you are using multithreading.

If you want to place the logic portion in a different class, you can subclass Thread directly, and then start a new object of this class when you press the button. The constructor of this subclass of Thread can receive a Queue object and then you will be able to communicate it with the GUI part. So my suggestion is:

1. Create a Queue object in the main thread
2. Create a new thread with access to that queue
3. Check periodically the queue in the main thread

Then you have to solve the problem of what happens if the user clicks two times the same button (it will spawn a new thread with each click), but you can fix it by disabling the start button and enabling it again after you call self.prog_bar.stop().

import Queue

class GUI:
    # ...

    def tb_click(self):
        self.progress()
        self.prog_bar.start()
        self.queue = Queue.Queue()
        ThreadedTask(self.queue).start()
        self.master.after(100, self.process_queue)

    def process_queue(self):
        try:
            msg = self.queue.get(0)
            # Show result of the task if needed
            self.prog_bar.stop()
        except Queue.Empty:
            self.master.after(100, self.process_queue)

class ThreadedTask(threading.Thread):
    def __init__(self, queue):
        threading.Thread.__init__(self)
        self.queue = queue
    def run(self):
        time.sleep(5)  # Simulate long running process
        self.queue.put("Task finished")

If you wish to have an GUI based broker testing without installing any tool you can use Hive Mqtt web socket for testing your Mosquitto server

just visit http://www.hivemq.com/demos/websocket-client/ and enter server connection details.

If you got connected means your server is configured properly.

You can also test publish and subscribe of messages using this mqtt web socket

Just collapse the table borders and remove the borders from table cells (td elements).

table {
    border: 1px solid #CCC;
    border-collapse: collapse;
}

td {
    border: none;
}

Without explicitly setting border-collapse cross-browser removal of table cell borders is not guaranteed.

I see that you are looking for an implementation of the problem more than solving that error. Here you have a possible solution:

from itertools import chain

def involved(courses, person):
    courses_info = chain.from_iterable(x.values() for x in courses.values())
    return filter(lambda x: x['teacher'] == person, courses_info)

print involved(courses, 'Dave')

The first thing I do is getting the list of the courses and then filter by teacher's name.

In the Terminal app, Preference >> Profiles tab.

Select the Shell tab on the right.

You can choose Never Ask before closing to suppress the warning.

I wanted to do the same thing as, but I wanted to do it in the one file.

So the logic would be:

• if a script with my name is running, kill it, then exit
• if a script with my name is not running, do stuff

I modified the answer by Bakuriu and came up with this:

from os import getpid
from sys import argv, exit
import psutil  ## pip install psutil

myname = argv[0]
mypid = getpid()
for process in psutil.process_iter():
    if process.pid != mypid:
        for path in process.cmdline():
            if myname in path:
                print "process found"
                process.terminate()
                exit()

## your program starts here...

Running the script will do whatever the script does. Running another instance of the script will kill any existing instance of the script.

I use this to display a little PyGTK calendar widget which runs when I click the clock. If I click and the calendar is not up, the calendar displays. If the calendar is running and I click the clock, the calendar disappears.

@bninopaul 's answer is not completely for beginners

here is the code you can "copy and run"

import seaborn as sn
import pandas as pd
import matplotlib.pyplot as plt

array = [[13,1,1,0,2,0],
         [3,9,6,0,1,0],
         [0,0,16,2,0,0],
         [0,0,0,13,0,0],
         [0,0,0,0,15,0],
         [0,0,1,0,0,15]]

df_cm = pd.DataFrame(array, range(6), range(6))
# plt.figure(figsize=(10,7))
sn.set(font_scale=1.4) # for label size
sn.heatmap(df_cm, annot=True, annot_kws={"size": 16}) # font size

plt.show()

My issue occurs when I add a PC to a domain. Restarting the service, making sure it's running, that it has the correct credentials to run, etc, as in other answers doesn't work. I don't know exactly what the problem is, but I can't even log in with the local user anymore to give the domain user access. Here's the steps that work for me:

In SSMS

• View > Registered Servers
• Database Engine > Local Server Groups > right-click pcname\sqlexpress
• Delete > Yes
• Right-click Local Server Groups > Tasks > Register Local Servers
• It confirms that it re-registered. pcname\sqlexpress reappears.

I'm then able to log in with the local windows auth'd user again, my databases are all there and everything. I then go about my business adding the domain user to Security > Logins.

I know this is an old post, but I found my way here in 2018, so maybe someone else will too. In my opinion, the OP had a better approach (using dgv_DataBindingComplete event) than any of the answers provided. At the time of writing, all of the answers are written using paint events or cellformatting events which seems inefficient.

The OP was 99% of the way there, all they had to do was loop through their rows, test the cell value of each row, and set the BackColor, ForeColor, or whatever other property you want to set.

Please excuse the vb.NET syntax, but I think its close enough to C# that it should be clear.

                    Else
                        row.Cells("COGS % Change").Style.ForeColor = Color.Red
                    End If

                    If grossProfitPercentChange > Single.Epsilon Then
                        row.Cells("Gross Profit % Change").Style.ForeColor = Color.Green
                    Else
                        row.Cells("Gross Profit % Change").Style.ForeColor = Color.Red
                    End If
                Next
            Catch ex As Exception
                Logging.ErrorHandler(ex)
            End Try
        End Sub

The best way is to check and then delete

        if (ctx.Employ.Any(r=>r.Id == entity.Id))
        {
            Employ rec = new Employ() { Id = entity.Id };
            ctx.Entry(rec).State = EntityState.Deleted;
            ctx.SaveChanges();
        }

To rename a table in SQL Server, use the sp_rename command:

exec sp_rename 'schema.old_table_name', 'new_table_name'

see http://api.jquery.com/prev/

var link = $("#me").parent("div").prev("h3").find("b");
alert(link.text());

see http://jsfiddle.net/gBwLq/

This is the best way, because if user not back more than two seconds then reset backpressed value.

declare one global variable.

 private boolean backPressToExit = false;

Override onBackPressed Method.

@Override
public void onBackPressed() {

    if (backPressToExit) {
        super.onBackPressed();
        return;
    }
    this.backPressToExit = true;
    Snackbar.make(findViewById(R.id.yourview), getString(R.string.exit_msg), Snackbar.LENGTH_SHORT).show();
    new Handler().postDelayed(new Runnable() {

        @Override
        public void run() {
            backPressToExit = false;
        }
    }, 2000);
}

Compare them as other values:

if($array_a == $array_b) {
  //they are the same
}

You can read about all array operators here: http://php.net/manual/en/language.operators.array.php Note for example that === also checks that the types and order of the elements in the arrays are the same.

Use Not IsEmpty().

For example:

Sub DoStuffIfNotEmpty()
    If Not IsEmpty(ActiveCell.Value) Then
        MsgBox "I'm not empty!"
    End If
End Sub

The best - and simplest - solution might be this:

Intent intent = new Intent(this, OtherActivity.class);
startActivity(intent);
finishAndRemoveTask();

Documentation for finishAndRemoveTask():

Call this when your activity is done and should be closed and the task should be completely removed as a part of finishing the root activity of the task.

Is that what you're looking for?

You can use the FromStr trait's from_str method, which is implemented for i32:

let my_num = i32::from_str("9").unwrap_or(0);

Gson gson = new Gson();
YourClass yourClassObject = new YourClass();
String jsonString = gson.toJson(yourClassObject);

Empty check on a JSON's key depends on use-case. For a common use-case, we can test for following:

1. Not null
2. Not undefined
3. Not an empty String ''
4. Not an empty Object {} [] (Array is an Object)

Function:

function isEmpty(arg){
  return (
    arg == null || // Check for null or undefined
    arg.length === 0 || // Check for empty String (Bonus check for empty Array)
    (typeof arg === 'object' && Object.keys(arg).length === 0) // Check for empty Object or Array
  );
}

Return true for:

isEmpty(''); // Empty String
isEmpty(null); // null
isEmpty(); // undefined
isEmpty({}); // Empty Object
isEmpty([]); // Empty Array

var ci = document.createElementNS("http://www.w3.org/2000/svg", "circle");

Personally, I would use XSLT to transform the XML and remove the trailing colons. For example, suppose I have this input:

<?xml version="1.0" encoding="UTF-8"?>
<Document>
    <Paragraph>This paragraph ends in a period.</Paragraph>
    <Paragraph>This one ends in a colon:</Paragraph>
    <Paragraph>This one has a : in the middle.</Paragraph>
</Document>

If I wanted to strip out trailing colons in my paragraphs, I would use this XSLT:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:fn="http://www.w3.org/2005/xpath-functions"
    version="2.0">
    <!-- identity -->
    <xsl:template match="/|@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
    <!-- strip out colons at the end of paragraphs -->
    <xsl:template match="Paragraph">
        <xsl:choose>
            <!-- if it ends with a : -->
            <xsl:when test="fn:ends-with(.,':')">
                <xsl:copy>
                    <!-- copy everything but the last character -->
                    <xsl:value-of select="substring(., 1, string-length(.)-1)"></xsl:value-of>
                </xsl:copy>
            </xsl:when>
            <xsl:otherwise>
                <xsl:copy>
                    <xsl:apply-templates/>
                </xsl:copy>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:template>
</xsl:stylesheet> 

I'd store it in the database as a BIGINT and I'd store the number of ticks (eg. TimeSpan.Ticks property).

That way, if I wanted to get a TimeSpan object when I retrieve it, I could just do TimeSpan.FromTicks(value) which would be easy.

Simplest solution: You're probably running out of virtual address space (any other form of error usually means running really slowly for a long time before you finally get a MemoryError). This is because a 32 bit application on Windows (and most OSes) is limited to 2 GB of user mode address space (Windows can be tweaked to make it 3 GB, but that's still a low cap). You've got 8 GB of RAM, but your program can't use (at least) 3/4 of it. Python has a fair amount of per-object overhead (object header, allocation alignment, etc.), odds are the strings alone are using close to a GB of RAM, and that's before you deal with the overhead of the dictionary, the rest of your program, the rest of Python, etc. If memory space fragments enough, and the dictionary needs to grow, it may not have enough contiguous space to reallocate, and you'll get a MemoryError.

Install a 64 bit version of Python (if you can, I'd recommend upgrading to Python 3 for other reasons); it will use more memory, but then, it will have access to a lot more memory space (and more physical RAM as well).

If that's not enough, consider converting to a sqlite3 database (or some other DB), so it naturally spills to disk when the data gets too large for main memory, while still having fairly efficient lookup.

This is a great article for syntax needed to create new objects from a LINQ query.

But, if the assignments to fill in the fields of the object are anything more than simple assignments, for example, parsing strings to integers, and one of them fails, it is not possible to debug this. You can not create a breakpoint on any of the individual assignments.

And if you move all the assignments to a subroutine, and return a new object from there, and attempt to set a breakpoint in that routine, you can set a breakpoint in that routine, but the breakpoint will never be triggered.

So instead of:

var query2 = from c in doc.Descendants("SuggestionItem")
                select new SuggestionItem
                       { Phrase = c.Element("Phrase").Value
                         Blocked = bool.Parse(c.Element("Blocked").Value),
                         SeenCount = int.Parse(c.Element("SeenCount").Value)
                       };

Or

var query2 = from c in doc.Descendants("SuggestionItem")
                         select new SuggestionItem(c);

I instead did this:

List<SuggestionItem> retList = new List<SuggestionItem>();

var query = from c in doc.Descendants("SuggestionItem") select c;

foreach (XElement item in query)
{
    SuggestionItem anItem = new SuggestionItem(item);
    retList.Add(anItem);
}

This allowed me to easily debug and figure out which assignment was failing. In this case, the XElement was missing a field I was parsing for to set in the SuggestionItem.

I ran into these gotchas with Visual Studio 2017 while writing unit tests for a new library routine.

A simple one liner:

$("#text").val( $("#text").val().replace(".", ":") );

Same problem here. Fixed! I installed the correct Java stuff, all for 64 bit, because my system is x64, and nothing happened. So I went to C:\Users\[my name] and deleted the directory .android that has been created the first time the SDK ran, apparently with some wrong configuration.

Then it worked. You can try that. Delete that folder or just move it to the desktop and run the SDK.

UCanAccess is a pure Java JDBC driver that allows us to read from and write to Access databases without using ODBC. It uses two other packages, Jackcess and HSQLDB, to perform these tasks. The following is a brief overview of how to get it set up.

Option 1: Using Maven

If your project uses Maven you can simply include UCanAccess via the following coordinates:

groupId: net.sf.ucanaccess
artifactId: ucanaccess

The following is an excerpt from pom.xml, you may need to update the <version> to get the most recent release:

  <dependencies>
    <dependency>
        <groupId>net.sf.ucanaccess</groupId>
        <artifactId>ucanaccess</artifactId>
        <version>4.0.4</version>
    </dependency>
  </dependencies>

Option 2: Manually adding the JARs to your project

As mentioned above, UCanAccess requires Jackcess and HSQLDB. Jackcess in turn has its own dependencies. So to use UCanAccess you will need to include the following components:

UCanAccess (ucanaccess-x.x.x.jar)
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
Jackcess (jackcess-2.x.x.jar)
commons-lang (commons-lang-2.6.jar, or newer 2.x version)
commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)

Fortunately, UCanAccess includes all of the required JAR files in its distribution file. When you unzip it you will see something like

ucanaccess-4.0.1.jar  
  /lib/
    commons-lang-2.6.jar  
    commons-logging-1.1.1.jar  
    hsqldb.jar  
    jackcess-2.1.6.jar

All you need to do is add all five (5) JARs to your project.

NOTE: Do not add loader/ucanload.jar to your build path if you are adding the other five (5) JAR files. The UcanloadDriver class is only used in special circumstances and requires a different setup. See the related answer here for details.

Eclipse: Right-click the project in Package Explorer and choose Build Path > Configure Build Path.... Click the "Add External JARs..." button to add each of the five (5) JARs. When you are finished your Java Build Path should look something like this

NetBeans: Expand the tree view for your project, right-click the "Libraries" folder and choose "Add JAR/Folder...", then browse to the JAR file.

After adding all five (5) JAR files the "Libraries" folder should look something like this:

IntelliJ IDEA: Choose File > Project Structure... from the main menu. In the "Libraries" pane click the "Add" (+) button and add the five (5) JAR files. Once that is done the project should look something like this:

That's it!

Now "U Can Access" data in .accdb and .mdb files using code like this

// assumes...
//     import java.sql.*;
Connection conn=DriverManager.getConnection(
        "jdbc:ucanaccess://C:/__tmp/test/zzz.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT [LastName] FROM [Clients]");
while (rs.next()) {
    System.out.println(rs.getString(1));
}

Disclosure

At the time of writing this Q&A I had no involvement in or affiliation with the UCanAccess project; I just used it. I have since become a contributor to the project.

Update:

if (localStorage.hasOwnProperty("username")) {
    //
}

Another way, relevant when value is not expected to be empty string, null or any other falsy value:

if (localStorage["username"]) {
    //
}

This class-based javascript animation works in AngularJS 1.2 (and 1.4 tested)

Edit: I ended up abandoning this code and went a completely different direction. I like my other answer much better. This answer will give you some problems in certain situations.

myApp.animation('.ng-show-toggle-slidedown', function(){
  return {
    beforeAddClass : function(element, className, done){
        if (className == 'ng-hide'){
            $(element).slideUp({duration: 400}, done);
        } else {done();}
    },
    beforeRemoveClass :  function(element, className, done){
        if (className == 'ng-hide'){
            $(element).css({display:'none'});
            $(element).slideDown({duration: 400}, done);
        } else {done();}
    }
}

});

Simply add the .ng-hide-toggle-slidedown class to the container element, and the jQuery slide down behavior will be implemented based on the ng-hide class.

You must include the $(element).css({display:'none'}) line in the beforeRemoveClass method because jQuery will not execute a slideDown unless the element is in a state of display: none prior to starting the jQuery animation. AngularJS uses the CSS

.ng-hide:not(.ng-hide-animate) {
    display: none !important;
}

to hide the element. jQuery is not aware of this state, and jQuery will need the display:none prior to the first slide down animation.

The AngularJS animation will add the .ng-hide-animate and .ng-animate classes while the animation is occuring.

No library is needed

Just pure JavaScript.

The example below gets the last two months from today:

var d = new Date()_x000D_
d.setMonth(d.getMonth() - 2);_x000D_
var dateString = new Date(d);_x000D_
console.log('Before Format', dateString, 'After format', dateString.toISOString().slice(0,10))

For situation, when "piping" is necessary you can use :

|&

For example:

echo -ne "15\n100\n"|sort -c |& tee >sort_result.txt

or

TIMEFORMAT=%R;for i in `seq 1 20` ; do time kubectl get pods |grep node >>js.log  ; done |& sort -h

This bash-based solutions can pipe STDOUT and STDERR separately (from STDERR of "sort -c" or from STDERR to "sort -h").

I made another variant with dropdown menu (perhaps for advanced search etc).. Here is how it looks like:

<div class="input-group my-4 col-6 mx-auto">
    <input class="form-control py-2 border-right-0 border" type="search" placeholder="Type something..." id="example-search-input">
    <span class="input-group-append">
        <button type="button" class="btn btn-outline-primary dropdown-toggle dropdown-toggle-split border border-left-0 border-right-0 rounded-0" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
            <span class="sr-only">Toggle Dropdown</span>
        </button>
        <button class="btn btn-outline-primary rounded-right" type="button">
            <i class="fas fa-search"></i>
        </button>
        <div class="dropdown-menu dropdown-menu-right">
            <a class="dropdown-item" href="#">Action</a>
            <a class="dropdown-item" href="#">Another action</a>
            <a class="dropdown-item" href="#">Something else here</a>
            <div role="separator" class="dropdown-divider"></div>
            <a class="dropdown-item" href="#">Separated link</a>
        </div>
    </span>
</div>

I was having the same issue while adding a mapbox navigation API and resolved this issue by going to: file>project Structure and then setting the compile sdk version and build tool version to the latest. And here is the screenshot:

Hope it helps.

In my case I had two problems:

1. My PC got a previous "Samsung Galaxy II" driver and assigned it to my Nexus 7. I needed uninstall it many times. Finally I could bind the correct Nexus 7 driver.

2. The need to set the PTP option.

All of the information you are looking for can be found here and here (thanks Reed Copsey):

From the first link:

Classes and structs that are declared directly within a namespace (in other words, that are not nested within other classes or structs) can be either public or internal. Internal is the default if no access modifier is specified.

...

The access level for class members and struct members, including nested classes and structs, is private by default.

...

interfaces default to internal access.

...

Delegates behave like classes and structs. By default, they have internal access when declared directly within a namespace, and private access when nested.

From the second link:

Top-level types, which are not nested in other types, can only have internal or public accessibility. The default accessibility for these types is internal.

And for nested types:

Members of    Default member accessibility
----------    ----------------------------
enum          public
class         private
interface     public
struct        private

I guess the core of your question is why to program to an interface, not to an implementation

Simply because an interface gives you more abstraction, and makes the code more flexible and resilient to changes, because you can use different implementations of the same interface(in this case you may want to change your List implementation to a linkedList instead of an ArrayList ) without changing its client.

1.press esc to enter the command mode 2.perss l(it L in lowcase) to show the line number

jQuery('#from_date').on('change', function(){
    var date = $(this).val();
    jQuery('#to_date').datetimepicker({minDate: date});  
});

Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

On input:

step="any"
class="two-decimals"

On script:

$(".two-decimals").change(function(){
  this.value = parseFloat(this.value).toFixed(2);
});

First of all, public static non-final fields are evil. Spring does not allow injecting to such fields for a reason.

Your workaround is valid, you don't even need getter/setter, private field is enough. On the other hand try this:

@Value("${my.name}")
public void setPrivateName(String privateName) {
    Sample.name = privateName;
}  

(works with @Autowired/@Resource). But to give you some constructive advice: Create a second class with private field and getter instead of public static field.

You can't import conditionally, but you can do the opposite: export something conditionally. It depends on your use case, so this work around might not be for you.

You can do:

api.js

import mockAPI from './mockAPI'
import realAPI from './realAPI'

const exportedAPI = shouldUseMock ? mockAPI : realAPI
export default exportedAPI

apiConsumer.js

import API from './api'
...

I use that to mock analytics libs like mixpanel, etc... because I can't have multiple builds or our frontend currently. Not the most elegant, but works. I just have a few 'if' here and there depending on the environment because in the case of mixpanel, it needs initialization.

See BigDecimal#intValue()

for objects/modules, you can also

'var' in dir(obj)

For example,

>>> class Something(object):
...     pass
...
>>> c = Something()
>>> c.a = 1
>>> 'a' in dir(c)
True
>>> 'b' in dir(c)
False

In my case I need to install more tools from Visual Studio (I'm using VS 2017 Community and Python 3.6.4). I installed those tools (see installer screenshot here):

1. Desktop development with C++: I included all defaulted items and the next ones:

   • Windows XP support for C++
   • Support for C++/CLI
   • VC++ 2015.3 v140 toolset

2. Linux development with C++

Then I opened the Windows PowerShell as Administrator privilegies (Right click to open) and move folder of Visual Studio installation and find that path:

cd [Visual Studio Path]\VC\Auxiliary\Build

Then I executed this file:

.\vcvars32.bat

After that I use pip as normal, for instance, I wanted to install Mayavi:

pip install mayavi

I hope that it helps someone too.

The itertools module has a useful method called permutations(). The documentation says:

itertools.permutations(iterable[, r])

Return successive r length permutations of elements in the iterable.

If r is not specified or is None, then r defaults to the length of the iterable and all possible full-length permutations are generated.

Permutations are emitted in lexicographic sort order. So, if the input iterable is sorted, the permutation tuples will be produced in sorted order.

You'll have to join your permuted letters as strings though.

>>> from itertools import permutations
>>> perms = [''.join(p) for p in permutations('stack')]
>>> perms

['stack', 'stakc', 'stcak', 'stcka', 'stkac', 'stkca', 'satck', 'satkc', 'sactk', 'sackt', 'saktc', 'sakct', 'sctak', 'sctka', 'scatk', 'scakt', 'sckta', 'sckat', 'sktac', 'sktca', 'skatc', 'skact', 'skcta', 'skcat', 'tsack', 'tsakc', 'tscak', 'tscka', 'tskac', 'tskca', 'tasck', 'taskc', 'tacsk', 'tacks', 'taksc', 'takcs', 'tcsak', 'tcska', 'tcask', 'tcaks', 'tcksa', 'tckas', 'tksac', 'tksca', 'tkasc', 'tkacs', 'tkcsa', 'tkcas', 'astck', 'astkc', 'asctk', 'asckt', 'asktc', 'askct', 'atsck', 'atskc', 'atcsk', 'atcks', 'atksc', 'atkcs', 'acstk', 'acskt', 'actsk', 'actks', 'ackst', 'ackts', 'akstc', 'aksct', 'aktsc', 'aktcs', 'akcst', 'akcts', 'cstak', 'cstka', 'csatk', 'csakt', 'cskta', 'cskat', 'ctsak', 'ctska', 'ctask', 'ctaks', 'ctksa', 'ctkas', 'castk', 'caskt', 'catsk', 'catks', 'cakst', 'cakts', 'cksta', 'cksat', 'cktsa', 'cktas', 'ckast', 'ckats', 'kstac', 'kstca', 'ksatc', 'ksact', 'kscta', 'kscat', 'ktsac', 'ktsca', 'ktasc', 'ktacs', 'ktcsa', 'ktcas', 'kastc', 'kasct', 'katsc', 'katcs', 'kacst', 'kacts', 'kcsta', 'kcsat', 'kctsa', 'kctas', 'kcast', 'kcats']

If you find yourself troubled by duplicates, try fitting your data into a structure with no duplicates like a set:

>>> perms = [''.join(p) for p in permutations('stacks')]
>>> len(perms)
720
>>> len(set(perms))
360

Thanks to @pst for pointing out that this is not what we'd traditionally think of as a type cast, but more of a call to the set() constructor.

This will be the simplest solution. I tried most of the solutions in the internet but only this helped me.

@print {
    @page :footer {
        display: none
    }

    @page :header {
        display: none
    }
}

Node.js 8.0.0 includes a new util.promisify() API that allows standard Node.js callback style APIs to be wrapped in a function that returns a Promise. An example use of util.promisify() is shown below.

const fs = require('fs');
const util = require('util');

const readFile = util.promisify(fs.readFile);

readFile('/some/file')
  .then((data) => { /** ... **/ })
  .catch((err) => { /** ... **/ });

You can get the results of SELECT SQL queries using from_statement() and text() as shown here. You don't have to deal with tuples this way. As an example for a class User having the table name users you can try,

from sqlalchemy.sql import text

user = session.query(User).from_statement(
    text("""SELECT * FROM users where name=:name""")
).params(name="ed").all()

return user

Taking reference of ThiefMaster? sometimes we get an error with value given as '\n' or null and perform for that required to handle ValueError:

Handling the exception is the way to go

try:
    gotdata = dlist[1]
except (IndexError, ValueError):
    gotdata = 'null'

Sometimes, you only need this code.

 httpClient.DefaultRequestHeaders.Add("token", token);

In my case i did following thing. In the UserMaster userId is PK and in UserAccess userId is FK of UserMaster

UserAccess.belongsTo(UserMaster,{foreignKey: 'userId'});
UserMaster.hasMany(UserAccess,{foreignKey : 'userId'});
var userData = await UserMaster.findAll({include: [UserAccess]});

Just wanted to add on to what @aioobe mentioned above...

In that approach you use HTML to color code your text. Though this is one of the most frequently used ways to color code the label text, but is not the most efficient way to do it.... considering that fact that each label will lead to HTML being parsed, rendering, etc. If you have large UI forms to be displayed, every millisecond counts to give a good user experience.

You may want to go through the below and give it a try....

This component is very easy to use. If you want to see a demo of their Swing Components you can run their WebStart demo located at www.jidesoft.com (http://www.jidesoft.com/products/1.4/jide_demo.jnlp). All of their offerings are demo'd... and best part is that the StyledLabel is compared with JLabel (HTML and without) in terms of speed! :-)

A screenshot of the perf test can be seen at (http://img267.imageshack.us/img267/9113/styledlabelperformance.png)

In TypeScript, you can do:

private getImage(imagePath): ng.IPromise<any> {
    var defer = this.q.defer<any>();
    var img = new Image();
    img.src = imagePath;
    img.addEventListener('load',()=>{
       defer.resolve(img);
    });


    return defer.promise;
} 

Use the above function to getimage object. Then the following to add to pdf file:

pdf.addImage(getImage(url), 'png', x, y, imagewidth, imageheight);

In plain JavaScript, the function looks like this:

function (imagePath) {
        var defer = this.q.defer();
        var img = new Image();
        img.src = imagePath;
        img.addEventListener('load', function () {
            defer.resolve(img);
        });
        return defer.promise;
    };

In Framework 2.0 you can use (It list files of root folder, it's best the most popular answer):

static void DirSearch(string dir)
{
    try
    {
        foreach (string f in Directory.GetFiles(dir))
            Console.WriteLine(f);
        foreach (string d in Directory.GetDirectories(dir))
        {
            Console.WriteLine(d);
            DirSearch(d);
        }

    }
    catch (System.Exception ex)
    {
        Console.WriteLine(ex.Message);
    }
}

if you want enable any extension then you have to install an extension first, extension maybe enabled but not installed so, taking example of bcmath

1.yum search php-bcmath

2.then ensure php version in which u want to install this extension

3.u will get output like after yum search command>>

yum search php-bcmath** Loaded plugins: fastestmirror, universal-hooks Loading mirror speeds from cached hostfile

then use >yum install ea-php72-php-bcmath.x86_64
5.this bcmath extension for php7.2
6.I wanna install for php71 then the command will be like **yum install ea-php71-php-bcmath.x86_64**  or yum install php71-bcmath.

7.u can install any extension from above steps.

As Except does not modify the list, you can use ForEach on List<T>:

list2.ForEach(item => list1.Remove(item));

It may not be the most efficient way, but it is simple, therefore readable, and it updates the original list (which is my requirement).

Check out "undoing changes" section of the svn book

I had a similar problem after I updated eclipse on Mavericks. Eventually I found that in the eclipse plugins directory the com.google.gdt.eclipse.login jar had version numbers at the end. I removed the version number from the name and it all started fine :)

In "pure" bash you have many tools for (sub)string manipulation, mainly, but not exclusively in parameter expansion :

${parameter//substring/replacement}
${parameter##remove_matching_prefix}
${parameter%%remove_matching_suffix}

Indexed substring expansion (special behaviours with negative offsets, and, in newer Bashes, negative lengths):

${parameter:offset}
${parameter:offset:length}
${parameter:offset:length}

And of course, the much useful expansions that operate on whether the parameter is null:

${parameter:+use this if param is NOT null}
${parameter:-use this if param is null}
${parameter:=use this and assign to param if param is null}
${parameter:?show this error if param is null}

They have more tweakable behaviours than those listed, and as I said, there are other ways to manipulate strings (a common one being $(command substitution) combined with sed or any other external filter). But, they are so easily found by typing man bash that I don't feel it merits to further extend this post.

If you can use extension methods, this will do it in a safe way regardless of string length:

public static string Right(this string text, int maxLength)
{
    if (string.IsNullOrEmpty(text) || maxLength <= 0)
    {
        return string.Empty;
    }

    if (maxLength < text.Length)
    {
        return text.Substring(text.Length - maxLength);
    }

    return text;
}

And to use it:

string sub = input.Right(5);

To simply list the commits waiting to be pushed: (this is the one you will remember)

git cherry -v

Show the commit subjects next to the SHA1s.

For me it was because of ipfs extension in brave browser

Did you try using SELECT PostGIS_version();

This is a possible solution for you:

a = [15, 12, 10]
b = sorted(a)
print b # --> b = [10, 12, 15]
c = 13
for i in range(len(b)):
    if b[i] > c:
        break
d = b[:i] + [c] + b[i:]
print d # --> d = [10, 12, 13, 15]

Usually when you want to check if a file exists, it's because you want to create that file if it doesn't. Graeme Perrow's answer is good if you don't want to create that file, but it's vulnerable to a race condition if you do: another process could create the file in between you checking if it exists, and you actually opening it to write to it. (Don't laugh... this could have bad security implications if the file created was a symlink!)

If you want to check for existence and create the file if it doesn't exist, atomically so that there are no race conditions, then use this:

#include <fcntl.h>
#include <errno.h>

fd = open(pathname, O_CREAT | O_WRONLY | O_EXCL, S_IRUSR | S_IWUSR);
if (fd < 0) {
  /* failure */
  if (errno == EEXIST) {
    /* the file already existed */
    ...
  }
} else {
  /* now you can use the file */
}

Try the following css:

#innerbox
{
   width:250px; /* or whatever width you want. */
   max-width:250px; /* or whatever width you want. */
   display: inline-block;
}

This makes the div take as little space as possible, and its width is defined by the css.

// Expanded answer

To make the buttons fixed widths do the following :

#innerbox input
{
   width:150px; /* or whatever width you want. */
   max-width:150px; /* or whatever width you want. */
}

However, you should be aware that as the size of the text changes, so does the space needed to display it. As such, it's natural that the containers need to expand. You should perhaps review what you are trying to do; and maybe have some predefined classes that you alter on the fly using javascript to ensure the content placement is perfect.

The solution which ultimately worked best for my organization is detailed below, it just adds a check on render for the sysadmin route and redirects the user to a different main path of the application if they are not allowed to be in the page.

SysAdminRoute.tsx

import React from 'react';
import { Route, Redirect, RouteProps } from 'react-router-dom';
import AuthService from '../services/AuthService';
import { appSectionPageUrls } from './appSectionPageUrls';
interface IProps extends RouteProps {}
export const SysAdminRoute = (props: IProps) => {
    var authService = new AuthService();
    if (!authService.getIsSysAdmin()) { //example
        authService.logout();
        return (<Redirect to={{
            pathname: appSectionPageUrls.site //front-facing
        }} />);
    }
    return (<Route {...props} />);
}

There are 3 main routes for our implementation, the public facing /site, the logged in client /app, and sys admin tools at /sysadmin. You get redirected based on your 'authiness' and this is the page at /sysadmin.

SysAdminNav.tsx

<Switch>
    <SysAdminRoute exact path={sysadminUrls.someSysAdminUrl} render={() => <SomeSysAdminUrl/> } />
    //etc
</Switch>

If you are not averse to using find, I like its -prune feature:

find [directory] \
        -name "pattern_to_exclude" -prune \
     -o -name "another_pattern_to_exclude" -prune \
     -o -name "pattern_to_INCLUDE" -print0 \
| xargs -0 -I FILENAME grep -IR "pattern" FILENAME

On the first line, you specify the directory you want to search. . (current directory) is a valid path, for example.

On the 2nd and 3rd lines, use "*.png", "*.gif", "*.jpg", and so forth. Use as many of these -o -name "..." -prune constructs as you have patterns.

On the 4th line, you need another -o (it specifies "or" to find), the patterns you DO want, and you need either a -print or -print0 at the end of it. If you just want "everything else" that remains after pruning the *.gif, *.png, etc. images, then use -o -print0 and you're done with the 4th line.

Finally, on the 5th line is the pipe to xargs which takes each of those resulting files and stores them in a variable FILENAME. It then passes grep the -IR flags, the "pattern", and then FILENAME is expanded by xargs to become that list of filenames found by find.

For your particular question, the statement may look something like:

find . \
     -name "*.png" -prune \
     -o -name "*.gif" -prune \
     -o -name "*.svn" -prune \
     -o -print0 | xargs -0 -I FILES grep -IR "foo=" FILES

You better do this syntax

if not (item in mylist):  
    Code inside the if

Here's a comprehensive yet non-exhaustive list of examples of list operations and whether or not they are thread safe. Hoping to get an answer regarding the obj in a_list language construct here.

A side from the very long complete accepted answer there is an important point to make about IndexOutOfRangeException compared with many other exception types, and that is:

Often there is complex program state that maybe difficult to have control over at a particular point in code e.g a DB connection goes down so data for an input cannot be retrieved etc... This kind of issue often results in an Exception of some kind that has to bubble up to a higher level because where it occurs has no way of dealing with it at that point.

IndexOutOfRangeException is generally different in that it in most cases it is pretty trivial to check for at the point where the exception is being raised. Generally this kind of exception get thrown by some code that could very easily deal with the issue at the place it is occurring - just by checking the actual length of the array. You don't want to 'fix' this by handling this exception higher up - but instead by ensuring its not thrown in the first instance - which in most cases is easy to do by checking the array length.

Another way of putting this is that other exceptions can arise due to genuine lack of control over input or program state BUT IndexOutOfRangeException more often than not is simply just pilot (programmer) error.

Just do this:

private void setImg(ImageView mImageView, Bitmap bitmap) {

    Drawable mDrawable = new BitmapDrawable(getResources(), bitmap);
    mImageView.setDrawable(mDrawable);
}

awk '{ sum += $2; n++ } END { if (n > 0) print sum / n; }'

Add the numbers in $2 (second column) in sum (variables are auto-initialized to zero by awk) and increment the number of rows (which could also be handled via built-in variable NR). At the end, if there was at least one value read, print the average.

awk '{ sum += $2 } END { if (NR > 0) print sum / NR }'

If you want to use the shebang notation, you could write:

#!/bin/awk

{ sum += $2 }
END { if (NR > 0) print sum / NR }

You can also control the format of the average with printf() and a suitable format ("%13.6e\n", for example).

You can also generalize the code to average the Nth column (with N=2 in this sample) using:

awk -v N=2 '{ sum += $N } END { if (NR > 0) print sum / NR }'

A good way to force your CSS to reload is to:

<link href='styles.css?version=1' rel='stylesheet'></link>

And then just increment the version number as you change your CSS. The browser will then obey. I believe StackOverflow uses this technique.

There is a fundamental concept of IP routing: You must have a unique IP address if you want your machine to be reachable via the Internet. This is called a "Public IP Address". "www.whatismyipaddress.com" will give you this. If your server is behind some default gateway, IP packets would reach you via that router. You can not be reached via your private IP address from the outside world. You should note that private IP addresses of client and server may be same as long as their corresponding default gateways have different addresses (that's why IPv4 is still in effect) I guess you're trying to ping from your private address of your client to the public IP address of the server (provided by whatismyipaddress.com). This is not feasible. In order to achieve this, a mapping from private to public address is required, a process called Network Address Translation or NAT in short. This is configured in Firewall or Router. You can create your own private network (say via wifi). In this case, since your client and server would be on the same logical network, no private to public address translation would be required and hence you can communicate using your private IP addresses only.

class Logo extends JPanel
{
    Logo()
    {
        //code
    }
    @Override
    public void paintComponent(Graphics g) 
    {
        super.paintComponent(g);
        ImageIcon img = new ImageIcon("logo.jpg");
        g.drawImage(img.getImage(), 0, 0, this.getWidth(), this.getHeight(), null);
    }
}

You can use preg_match to match the part of the URL that you want.

In this case, since the pattern is easy, we're looking for a forward slash (\/ and we have to escape it since the forward slash denotes the beginning and end of the regular expression pattern), along with one or more digits (\d+) at the very end of the string ($). The parentheses around the \d+ are used for capturing the piece that we want: namely the end. We then assign the ending that we want ($end) to $matches[1] (not $matches[0], since that is the same as $url (ie the entire string)).

$url='http://domain.com/artist/song/music-videos/song-title/9393903';

if(preg_match("/\/(\d+)$/",$url,$matches))
{
  $end=$matches[1];
}
else
{
  //Your URL didn't match.  This may or may not be a bad thing.
}

Note: You may or may not want to add some more sophistication to this regular expression. For example, if you know that your URL strings will always start with http:// then the regex can become /^http:\/\/.*\/(\d+)$/ (where .* means zero or more characters (that aren't the newline character)).

Use this expression:

/\(([^()]+)\)/g

e.g:

function()
{
    var mts = "something/([0-9])/([a-z])".match(/\(([^()]+)\)/g );
    alert(mts[0]);
    alert(mts[1]);
}

Maybe this helps someone.

here is the solution for similar problem which i was facing while extracting name from user profile facebook json object

$uname=json_encode($userprof);
$uname=json_decode($uname);
echo "Welcome " . $uname -> name  ;

char[] ch = ?
new String(ch).getBytes();

or

new String(ch).getBytes("UTF-8");

to get non-default charset.

Update: Since Java 7: new String(ch).getBytes(StandardCharsets.UTF_8);

Ok, looks like your post got editted...

double foo[4];
double *bar_1 = &foo[0];

See how you can use the & to get the address of the beginning of the array structure? The following

Foo_1(double *bar, int size){ return bar[size-1]; }
Foo_2(double bar[], int size){ return bar[size-1]; }

will do the same thing.

The primary difference is that SELECT INTO MyTable will create a new table called MyTable with the results, while INSERT INTO requires that MyTable already exists.

You would use SELECT INTO only in the case where the table didn't exist and you wanted to create it based on the results of your query. As such, these two statements really are not comparable. They do very different things.

In general, SELECT INTO is used more often for one off tasks, while INSERT INTO is used regularly to add rows to tables.

EDIT:
While you can use CREATE TABLE and INSERT INTO to accomplish what SELECT INTO does, with SELECT INTO you do not have to know the table definition beforehand. SELECT INTO is probably included in SQL because it makes tasks like ad hoc reporting or copying tables much easier.

Here is what i did for uploading photo using post request.

public void uploadFile(int directoryID, String filePath) {
    Bitmap bitmapOrg = BitmapFactory.decodeFile(filePath);
    ByteArrayOutputStream bao = new ByteArrayOutputStream();

    String upload_url = BASE_URL + UPLOAD_FILE;
    bitmapOrg.compress(Bitmap.CompressFormat.JPEG, 90, bao);

    byte[] data = bao.toByteArray();

    HttpClient httpClient = new DefaultHttpClient();
    HttpPost postRequest = new HttpPost(upload_url);
    MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

    try {
        // Set Data and Content-type header for the image
        FileBody fb = new FileBody(new File(filePath), "image/jpeg");
        StringBody contentString = new StringBody(directoryID + "");

        entity.addPart("file", fb);
        entity.addPart("directory_id", contentString);
        postRequest.setEntity(entity);

        HttpResponse response = httpClient.execute(postRequest);
        // Read the response
        String jsonString = EntityUtils.toString(response.getEntity());
        Log.e("response after uploading file ", jsonString);

    } catch (Exception e) {
        Log.e("Error in uploadFile", e.getMessage());
    }
}

NOTE: This code requires libraries so Follow the instructions here in order to get the libraries.

Here is an option using dplyr. The %<>% operator from magrittr update the lhs object with the resulting value.

library(magrittr)
library(dplyr)
cols <- c("A", "C", "D", "H")

data %<>%
       mutate_each_(funs(factor(.)),cols)
str(data)
#'data.frame':  4 obs. of  10 variables:
# $ A: Factor w/ 4 levels "23","24","26",..: 1 2 3 4
# $ B: int  15 13 39 16
# $ C: Factor w/ 4 levels "3","5","18","37": 2 1 3 4
# $ D: Factor w/ 4 levels "2","6","28","38": 3 1 4 2
# $ E: int  14 4 22 20
# $ F: int  7 19 36 27
# $ G: int  35 40 21 10
# $ H: Factor w/ 4 levels "11","29","32",..: 1 4 3 2
# $ I: int  17 1 9 25
# $ J: int  12 30 8 33

Or if we are using data.table, either use a for loop with set

setDT(data)
for(j in cols){
  set(data, i=NULL, j=j, value=factor(data[[j]]))
}

Or we can specify the 'cols' in .SDcols and assign (:=) the rhs to 'cols'

setDT(data)[, (cols):= lapply(.SD, factor), .SDcols=cols]

Base on Leo's answer, add

• Support for negative
• Support 0 < value < 1 ( Ex: 0.2, will cause log(value) = negative number )

If you want max unit to Mega, change to $units = explode(' ', ' K M');

function formatUnit($value, $precision = 2) {
    $units = explode(' ', ' K M G T P E Z Y');

    if ($value < 0) {
        return '-' . formatUnit(abs($value));
    }

    if ($value < 1) {
        return $value . $units[0];
    }

    $power = min(
        floor(log($value, 1024)),
        count($units) - 1
    );

    return round($value / pow(1024, $power), $precision) . $units[$power];
}

Use six:

Have you tried using the stream_context_set_option() method ?

$context = stream_context_create();
$result = stream_context_set_option($context, 'ssl', 'local_cert', '/etc/ssl/certs/cacert.pem');
$fp = fsockopen($host, $port, $errno, $errstr, 20, $context);

In addition, try file_get_contents() for the pem file, to make sure you have permissions to access it, and make sure the host name matches the certificate.

I'm facing this from file://. I'd like to send queries to two servers from a local HTML file (a testbed).

This particular case should not be any safety concern, but only Safari allows this.

Here is the best discussion I've found of the issue.

If you want to use @Html.EditorFor() you have to use jQuery ui and update your Asp.net Mvc to 5.2.6.0 with NuGet Package Manager.

@Html.EditorFor(m => m.EntryDate, new { htmlAttributes = new { @class = "datepicker" } })

@section Scripts {

@Scripts.Render("~/bundles/jqueryval")

<script>

    $(document).ready(function(){

      $('.datepicker').datepicker();

     });

</script>

}

For Java Developers:

As @Niels said you have to place in values-v21/styles.xml:

<item name="android:statusBarColor">@color/black</item>

But add tools:targetApi="lollipop" if you want single styles.xml, like:

<item name="android:statusBarColor" tools:targetApi="lollipop">@color/black</item>

For Kotlin Developers:

window.statusBarColor = ContextCompat.getColor(this, R.color.color_name)

The answers above are great. If you are in need of parsing all numbers out of a string that are nonconsecutive then the following may be of some help:

string input = "1-205-330-2342";
string result = Regex.Replace(input, @"[^\d]", "");
Console.WriteLine(result); // >> 12053302342

You can go fullscreen automatically by putting this code in:

var elem = document.documentElement; if (elem.requestFullscreen) { elem.requestFullscreen() }

note: does not always work for security reasons. but it works for me at least. does not work when inspecting and pasting the code.

Since git 1.8.5 (Q4 2013):

"git fetch" (hence "git pull" as well) learned to check "fetch.prune" and "remote.*.prune" configuration variables and to behave as if the "--prune" command line option was given.

That means that, if you set remote.origin.prune to true:

git config remote.origin.prune true

Any git fetch or git pull will automatically prune.

Note: Git 2.12 (Q1 2017) will fix a bug related to this configuration, which would make git remote rename misbehave.
See "How do I rename a git remote?".

See more at commit 737c5a9:

Without "git fetch --prune", remote-tracking branches for a branch the other side already has removed will stay forever.
Some people want to always run "git fetch --prune".

To accommodate users who want to either prune always or when fetching from a particular remote, add two new configuration variables "fetch.prune" and "remote.<name>.prune":

• "fetch.prune" allows to enable prune for all fetch operations.
• "remote.<name>.prune" allows to change the behaviour per remote.

The latter will naturally override the former, and the --[no-]prune option from the command line will override the configured default.

Since --prune is a potentially destructive operation (Git doesn't keep reflogs for deleted references yet), we don't want to prune without users consent, so this configuration will not be on by default.

To be clear, you don't want a "fast way to move the cursor on a terminal command line". What you actually want is a fast way to navigate over command line in you shell program.

Bash is very common shell, for example. It uses Readline library to implement command line input. And so to say, it is very convenient to know Readline bindings since it is used not only in bash. For example, gdb also uses Readline to process input.

In Readline documentation you can find all navigation related bindings (and more): http://www.gnu.org/software/bash/manual/bash.html#Readline-Interaction

Short copy-paste if the link above goes down:

Bare Essentials

• Ctrl-b Move back one character.
• Ctrl-f Move forward one character.
• [DEL] or [Backspace] Delete the character to the left of the cursor.
• Ctrl-d Delete the character underneath the cursor.
• Ctrl-_ or C-x C-u Undo the last editing command. You can undo all the way back to an empty line.

Movement

• Ctrl-a Move to the start of the line.
• Ctrl-e Move to the end of the line.
• Meta-f Move forward a word, where a word is composed of letters and digits.
• Meta-b Move backward a word.
• Ctrl-l Clear the screen, reprinting the current line at the top.

Kill and yank

• Ctrl-k Kill the text from the current cursor position to the end of the line.
• M-d Kill from the cursor to the end of the current word, or, if between words, to the end of the next word. Word boundaries are the same as those used by M-f.
• M-[DEL] Kill from the cursor the start of the current word, or, if between words, to the start of the previous word. Word boundaries are the same as those used by M-b.
• Ctrl-w Kill from the cursor to the previous whitespace. This is different than M- because the word boundaries differ.
• Ctrl-y Yank the most recently killed text back into the buffer at the cursor.
• M-y Rotate the kill-ring, and yank the new top. You can only do this if the prior command is C-y or M-y.

M is Meta key. For Max OS X Terminal you can enable "Use option as meta key" in Settings/Keyboard for that. For Linux its more complicated.

Update

Also note, that Readline can operate in two modes:

• emacs mode (which is the default)
• vi mode

To switch Bash to use vi mode:

$ set -o vi

Personaly I prefer vi mode since I use vim for text editing.

Bonus

In macOS Terminal app (and in iTerm too) you can Option-Click to move the cursor (cursor will move to clicked position). This even works inside vim.

This is quicker. Just use this

No documentation exists, but I got it from the gollum documentation. Looking at rubydoc.info, it looks like you can use:

require 'github/markdown'  
puts GitHub::Markdown.render_gfm('your markdown string')

in your Ruby code. You can wrap that easily in a script to turn it into a command line utility:

#!/usr/bin/env ruby

# render.rb
require 'github/markdown'

puts GitHub::Markdown.render_gfm File.read(ARGV[0])

Execute it with ./render.rb path/to/my/markdown/file.md. Note that this is not safe for use in production without sanitization.

I used @qwertyjones's answer to automate logging into Oracle Agile with a public password.

I saved the login page as index.html, edited all the href= and action= fields to have the full URL to the Agile server.

The key <form> line needed to change from

<form autocomplete="off" name="MainForm" method="POST"
 action="j_security_check" 
 onsubmit="return false;" target="_top">

to

<form autocomplete="off" name="MainForm" method="POST"
 action="http://my.company.com:7001/Agile/default/j_security_check"   
 onsubmit="return false;" target="_top">

I also added this snippet to the end of the <body>

<script>
function checkCookiesEnabled(){ return true; }
document.MainForm.j_username.value = "joeuser";
document.MainForm.j_password.value = "abcdef";
submitLoginForm();
</script> 

I had to disable the cookie check by redefining the function that did the check, because I was hosting this from XAMPP and I didn't want to deal with it. The submitLoginForm() call was inspired by inspecting the keyPressEvent() function.

This works:

Object firstElement = set.toArray()[0]; 

I have the following config in my private project:

git config alias.auto 'commit -a -m "changes made from [device name]"'

That way, when I'm in a hurry I do

git auto
git push

And at least I know what device the commit was made from.

A simple way to do this is using ifelse, which is vectorized. If the condition is satisfied, we use a replacement value, otherwise we use the original value.

v <- c(3, 2, 1, 0, 4, 0)
ifelse(v == 0, 1, v)

We can avoid a named variable by using a pipe.

c(3, 2, 1, 0, 4, 0) %>% ifelse(. == 0, 1, .)

A common task is to do multiple replacements. Instead of nested ifelse statements, we can use case_when from dplyr:

case_when(v == 0 ~ 1,
          v == 1 ~ 2,
          TRUE ~ v)

Old answer:

For factor or character vectors, we can use revalue from plyr:

> revalue(c("a", "b", "c"), c("b" = "B"))
[1] "a" "B" "c"

This has the advantage of only specifying the input vector once, so we can use a pipe like

x %>% revalue(c("b" = "B"))

You've already got a working answer but just in case you are curious what was wrong with your original approach, the answer is that you need parentheses around your alternation otherwise the (\.|$) is only required if the number is less than 200.

'\b((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)(\.|$)){4}\b'
    ^                                    ^

I know this question is old but I ran across it and I know other people might have the same problem. All these answers are okay but do not give proper detail or actual TRUE advice.

When wanting to style a specific section of a paragraph use the span tag.

<p><span style="font-weight:900">Andy Warhol</span> (August 6, 1928 - February 22, 1987) 

was an American artist who was a leading figure in the visual art movement known as pop 

art.</p>

Andy Warhol (August 6, 1928 - February 22, 1987) was an American artist who was a leading figure in the visual art movement known as pop art.

As the code shows, the span tag styles on the specified words: "Andy Warhol". You can further style a word using any CSS font styling codes.

{font-weight; font-size; text-decoration; font-family; margin; color}, etc. 

Any of these and more can be used to style a word, group of words, or even specified paragraphs without having to add a class to the CSS Style Sheet Doc. I hope this helps someone!

The LEA instruction can be used to avoid time consuming calculations of effective addresses by the CPU. If an address is used repeatedly it is more effective to store it in a register instead of calculating the effective address every time it is used.

A today extension would be the most fitting solution.

Also you could do something on the lock screen with local notifications queued up to fire at regular intervals showing the latest countdown value.

You can do this simply by using pandas drop duplicates function

df.drop_duplicates(['A','B'],keep= 'last')

Since you actually want a different array which is arr where arr < 255, and 255 otherwise, this can be done simply:

result = np.minimum(arr, 255)

More generally, for a lower and/or upper bound:

result = np.clip(arr, 0, 255)

If you just want to access the values over 255, or something more complicated, @mtitan8's answer is more general, but np.clip and np.minimum (or np.maximum) are nicer and much faster for your case:

In [292]: timeit np.minimum(a, 255)
100000 loops, best of 3: 19.6 µs per loop

In [293]: %%timeit
   .....: c = np.copy(a)
   .....: c[a>255] = 255
   .....: 
10000 loops, best of 3: 86.6 µs per loop

If you want to do it in-place (i.e., modify arr instead of creating result) you can use the out parameter of np.minimum:

np.minimum(arr, 255, out=arr)

or

np.clip(arr, 0, 255, arr)

(the out= name is optional since the arguments in the same order as the function's definition.)

For in-place modification, the boolean indexing speeds up a lot (without having to make and then modify the copy separately), but is still not as fast as minimum:

In [328]: %%timeit
   .....: a = np.random.randint(0, 300, (100,100))
   .....: np.minimum(a, 255, a)
   .....: 
100000 loops, best of 3: 303 µs per loop

In [329]: %%timeit
   .....: a = np.random.randint(0, 300, (100,100))
   .....: a[a>255] = 255
   .....: 
100000 loops, best of 3: 356 µs per loop

For comparison, if you wanted to restrict your values with a minimum as well as a maximum, without clip you would have to do this twice, with something like

np.minimum(a, 255, a)
np.maximum(a, 0, a)

or,

a[a>255] = 255
a[a<0] = 0

REST vs. SOAP Web Services

I am seeing a lot of new web services are implemented using a REST style architecture these days rather than a SOAP one. Lets step back a second and explain what REST is.

What is a REST web service?

The acronym REST stands for representational state transfer, and this basically means that each unique URL is a representation of some object. You can get the contents of that object using an HTTP GET, to delete it, you then might use a POST, PUT, or DELETE to modify the object (in practice most of the services use a POST for this).

Who's using REST?

All of Yahoo's web services use REST, including Flickr and Delicious.

APIs use it, pubsub, bloglines, Technorati, and both eBay, and Amazon have web services for both REST and SOAP.

Who's using SOAP?

Google seams to be consistent in implementing their web services to use SOAP, with the exception of Blogger, which uses XML-RPC. You will find SOAP web services in lots of enterprise software as well.

REST vs. SOAP

As you may have noticed the companies I mentioned that are using REST APIs haven't been around for very long, and their APIs came out this year mostly. So REST is definitely the trendy way to create a web service, if creating web services could ever be trendy (lets face it you use soap to wash, and you rest when your tired). The main advantages of REST web services are:

• Lightweight - not a lot of extra XML markup Human Readable Results

• Easy to build - no toolkits required. SOAP also has some advantages:

Easy to consume - sometimes Rigid - type checking, adheres to a contract Development tools For consuming web services, its sometimes a toss up between which is easier. For instance Google's AdWords web service is really hard to consume (in ColdFusion anyway), it uses SOAP headers, and a number of other things that make it kind of difficult. On the converse, Amazon's REST web service can sometimes be tricky to parse because it can be highly nested, and the result schema can vary quite a bit based on what you search for.

Whichever architecture you choose make sure its easy for developers to access it, and well documented.

Java is considered "row major", meaning that it does rows first. This is because a 2D array is an "array of arrays".

For example:

int[ ][ ] a = new int[2][4];  // Two rows and four columns.

a[0][0] a[0][1] a[0][2] a[0][3]

a[1][0] a[1][1] a[1][2] a[1][3]

It can also be visualized more like this:

a[0] ->  [0] [1] [2] [3]
a[1] ->  [0] [1] [2] [3]

The second illustration shows the "array of arrays" aspect. The first array contains {a[0] and a[1]}, and each of those is an array containing four elements, {[0][1][2][3]}.

TL;DR summary:

Array[number of arrays][how many elements in each of those arrays]

For more explanations, see also Arrays - 2-dimensional.

You should use what your FPGA documentation recommends. There is no portable way to initialize register values other than using a reset net. This has a hardware cost associated with it on most synthesis targets.

Please set the request Content Type before you read the response stream;

 request.ContentType = "text/xml";

I'm not sure about a way to do it directly with AngularJS but you could set the display to none for both welcome and login and animate the opacity with an directive once they are loaded.

I would do it some way like so. 2 Directives for fading in the content and fading it out when a link is clicked. The directive for fadeouts could simply animate a element with an unique ID or call a service which broadcasts the fadeout

Template:

<div class="tmplWrapper" onLoadFadeIn>
    <a href="somewhere/else" fadeOut>
</div>

Directives:

angular
  .directive('onLoadFadeIn', ['Fading', function('Fading') {
    return function(scope, element, attrs) {
      $(element).animate(...);
      scope.$on('fading', function() {
    $(element).animate(...);
      });
    }
  }])
  .directive('fadeOut', function() {
    return function(scope, element, attrs) {
      element.bind('fadeOut', function(e) {
    Fading.fadeOut(e.target);
  });
    }
  });

Service:

angular.factory('Fading', function() {
  var news;
  news.setActiveUnit = function() {
    $rootScope.$broadcast('fadeOut');
  };
  return news;
})

I just have put together this code quickly so there may be some bugs :)

Use the FormBorderStyle property. Make it FixedSingle:

this.FormBorderStyle = FormBorderStyle.FixedSingle;

Try this

df.drop(df.iloc[:, 1:69], inplace=True, axis=1)

This works for me

Try sudo npm uninstall cordova -g to uninstall it globally and then just npm install cordova without the -g flag after cding to the local app directory

The new way to do with c++20 is using format.

#include <format>

auto var = std::format("sometext {} sometext {}", somevar, somevar);

David Walsh has a nice solution for this. Here is my take on this, combining his solution with what has been discovered on this thread as well.

https://davidwalsh.name/global-variables-javascript

x = {};
var iframe = document.createElement('iframe');
iframe.onload = function() {
    var standardGlobals = Object.keys(iframe.contentWindow);
    for(var b in window) { 
      const prop = window[b];
      if(window.hasOwnProperty(b) && prop && !prop.toString().includes('native code') && !standardGlobals.includes(b)) {
        x[b] = prop;
      }
    }
    console.log(x)
};
iframe.src = 'about:blank';
document.body.appendChild(iframe);

x now has only the globals.

Suppose you want to check a boolean. If true, do something. Else, do something else. You can write:

if(condition==true){

}
else{   //else means this checks for the opposite of what you checked at if

}

instead of that, you can do it simply like:

if(condition){  //this will check if condition is true 

}
else{ 

}

Inversely. If you were to do something if condition was false and do something else if condition was true. Then you would write:

if(condition!=true){   //if(condition=false)

}
else{

}

But following the simple path. We do:

if(!condition){  //it reads out as: if condition is not true. Which means if condition is false right?

}
else{

}

Think about it. You'll get it in no time.

To run a select from where field is in list of strings (instead of int), as per this question use repr(tuple(map(str, l))). Full example:

l = ['a','b','c']
sql = f'''

select name 
from students 
where id in {repr(tuple(map(str, l)))}
'''
print(sql)

Returns: select name from students where id in ('a', 'b', 'c')

For a list of dates in Oracle, this worked

dates_str = ','.join([f'DATE {repr(s)}' for s in ['2020-11-24', '2020-12-28']])
dates_str = f'({dates_str})'

sql_cmd = f'''
select *
from students 
where 
and date in {dates_str}
'''

Returns: select * from students where and date in (DATE '2020-11-24',DATE '2020-12-28')

If you are only comparing objects of the same type or further down the inheritance chain, why not specify the parameter as your base type, rather than object ?

Also do null checks on the parameter as well.

Furthermore I'd make use of 'var' just to make the code more readable (if its c#3 code)

Also, if the object has reference types as properties then you are just calling ToString() on them which doesn't really compare values. If ToString isn't overwridden then its just going to return the type name as a string which could return false-positives.

For future reference Python is strongly typed. Unlike other dynamic languages, it will not automagically cast objects from one type or the other (say from str to int) so you must do this yourself. You'll like that in the long-run, trust me!

If this is your detail.html I don't see where do you load detail.js? Maybe this

<script src="js/index.js"></script>

should be this

<script src="js/detail.js"></script>

?

 //This is The easiest I can Imagine . 
 // You need to just change the order of Columns and rows , Yours is printing columns X rows and the solution is printing them rows X columns 
for(int rows=0;rows<array.length;rows++){
    for(int columns=0;columns <array[rows].length;columns++){
        System.out.print(array[rows][columns] + "\t" );}
    System.out.println();}

request.getAttribute("servletName") method will return Object that you need to cast to ArrayList

ArrayList<Category> list =new ArrayList<Category>();
//storing passed value from jsp
list = (ArrayList<Category>)request.getAttribute("servletName");

names = [];
$('input[name=text], textarea').each(
    function(index){  
        var input = $(this);
        names.push( input.attr('name') );
        //input.attr('id');
    }
);

it select all textboxes and textarea in your DOM, where $.each function iterates to provide name of ecah element.

I suppose you don't want to change get_sublist function, and just want to use DataFrame's apply method to do the job. To get the result you want, I've wrote two help functions: get_sublist_list and unlist. As the function name suggest, first get the list of sublist, second extract that sublist from that list. Finally, We need to call apply function to apply those two functions to the df[['col_1','col_2']] DataFrame subsequently.

import pandas as pd

df = pd.DataFrame({'ID':['1','2','3'], 'col_1': [0,2,3], 'col_2':[1,4,5]})
mylist = ['a','b','c','d','e','f']

def get_sublist(sta,end):
    return mylist[sta:end+1]

def get_sublist_list(cols):
    return [get_sublist(cols[0],cols[1])]

def unlist(list_of_lists):
    return list_of_lists[0]

df['col_3'] = df[['col_1','col_2']].apply(get_sublist_list,axis=1).apply(unlist)

df

If you don't use [] to enclose the get_sublist function, then the get_sublist_list function will return a plain list, it'll raise ValueError: could not broadcast input array from shape (3) into shape (2), as @Ted Petrou had mentioned.

I would use a decimal with the proper precision for your data.

You need astype:

df['zipcode'] = df.zipcode.astype(str)
#df.zipcode = df.zipcode.astype(str)

For converting to categorical:

df['zipcode'] = df.zipcode.astype('category')
#df.zipcode = df.zipcode.astype('category')

Another solution is Categorical:

df['zipcode'] = pd.Categorical(df.zipcode)

Sample with data:

import pandas as pd

df = pd.DataFrame({'zipcode': {17384: 98125, 2680: 98107, 722: 98005, 18754: 98109, 14554: 98155}, 'bathrooms': {17384: 1.5, 2680: 0.75, 722: 3.25, 18754: 1.0, 14554: 2.5}, 'sqft_lot': {17384: 1650, 2680: 3700, 722: 51836, 18754: 2640, 14554: 9603}, 'bedrooms': {17384: 2, 2680: 2, 722: 4, 18754: 2, 14554: 4}, 'sqft_living': {17384: 1430, 2680: 1440, 722: 4670, 18754: 1130, 14554: 3180}, 'floors': {17384: 3.0, 2680: 1.0, 722: 2.0, 18754: 1.0, 14554: 2.0}})

The answer of delfuego is the simplest way to solve the certificate problem. But, in my case, one of our third party url (using https), updated their certificate every 2 months automatically. It means that I have to import the cert to our Java trust store manually every 2 months as well. Sometimes it caused production problems.

So, I made a method to solve it with SecureRestClientTrustManager to be able to consume https url without importing the cert file. Here is the method:

     public static String doPostSecureWithHeader(String url, String body, Map headers)
            throws Exception {
        log.info("start doPostSecureWithHeader " + url + " with param " + body);
        long startTime;
        long endTime;
        startTime = System.currentTimeMillis();
        Client client;
        client = Client.create();
        WebResource webResource;
        webResource = null;
        String output = null;
        try{
            SSLContext sslContext = null;
            SecureRestClientTrustManager secureRestClientTrustManager = new SecureRestClientTrustManager();
            sslContext = SSLContext.getInstance("SSL");
            sslContext
            .init(null,
                    new javax.net.ssl.TrustManager[] { secureRestClientTrustManager },
                    null);
            DefaultClientConfig defaultClientConfig = new DefaultClientConfig();
            defaultClientConfig
            .getProperties()
            .put(com.sun.jersey.client.urlconnection.HTTPSProperties.PROPERTY_HTTPS_PROPERTIES,
                    new com.sun.jersey.client.urlconnection.HTTPSProperties(
                            getHostnameVerifier(), sslContext));

            client = Client.create(defaultClientConfig);
            webResource = client.resource(url);

            if(headers!=null && headers.size()>0){
                for (Map.Entry entry : headers.entrySet()){
                    webResource.setProperty(entry.getKey(), entry.getValue());
                }
            }
            WebResource.Builder builder = 
                    webResource.accept("application/json");
            if(headers!=null && headers.size()>0){
                for (Map.Entry entry : headers.entrySet()){
                    builder.header(entry.getKey(), entry.getValue());
                }
            }

            ClientResponse response = builder
                    .post(ClientResponse.class, body);
            output = response.getEntity(String.class);
        }
        catch(Exception e){
            log.error(e.getMessage(),e);
            if(e.toString().contains("One or more of query value parameters are null")){
                output="-1";
            }
            if(e.toString().contains("401 Unauthorized")){
                throw e;
            }
        }
        finally {
            if (client!= null) {
                client.destroy();
            }
        }
        endTime = System.currentTimeMillis();
        log.info("time hit "+ url +" selama "+ (endTime - startTime) + " milliseconds dengan output = "+output);
        return output;
    }

this usage may solve your problem.

If you do not need the Visual Studio Hosting Process:

Uncheck the option: Project->Properties->Debug->Enable the Visual Studio Hosting Process

And then build.

If you still face the problem:

Go to Project->Properties->Build Events->Post-Build Event Command line and paste the following:

call "$(DevEnvDir)..\..\vc\vcvarsall.bat" x86
"$(DevEnvDir)..\..\vc\bin\EditBin.exe" "$(TargetPath)"  /LARGEADDRESSAWARE

Now, build the project.

If you use a full screen table you are maybe interested in setting th to display:fixed; and top:0; or try a very similar approach via css.

Update

Just quickly build up a working solution with iframes (html4.0). This example IS NOT standard conform, however you will easily be able to fix it:

outer.html

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">   
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">     
    <head>      
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />   
        <title>Outer</title>
  <body>
    <iframe src="test.html" width="200" height="100"></iframe>
    </body>
</html> 

test.html

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">   
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">     
    <head>      
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />   
        <title>Floating</title>
    <style type="text/css">
      .content{
        position:relative; 
      }

      thead{
        background-color:red;
        position:fixed; 
        top:0;
      }
    </style>
  <body>
    <div class="content">      
      <table>
        <thead>
          <tr class="top"><td>Title</td></tr>
        </head>
        <tbody>
          <tr><td>a</td></tr>
          <tr><td>b</td></tr>
          <tr><td>c</td></tr>
          <tr><td>d</td></tr>
          <tr><td>e</td></tr>
          <tr><td>e</td></tr>
          <tr><td>e</td></tr>
          <tr><td>e</td></tr>
          <tr><td>e</td></tr>
          <tr><td>e</td></tr>
        </tbody>
      </table>
    </div>
    </body>
</html> 

ExecuteScalar() is what you need here
